Gu Chen probably figured out the situation, and co-authored Aunt Liu was rescued by a dog yesterday.

I am also glad that Aunt Liu still has a dog by her side......

For a person with an arrogant personality like her, she usually has no friends around her at all, and she lives alone.

If something really happens, she really can't expect the neighbors to help her.

But fortunately, Aunt Liu changed her indifference to people to her enthusiasm for dogs.

Thankfully, she was able to escape with the help of little Teddy......

Otherwise, it is difficult to say that you will starve to death, and it will be difficult to say that you will not be discovered for a year or two.

"That is to say, with the help of Xiaobao, you untied the rope and then came to the hospital by yourself?" Gu Chen asked her again with confirmation.

Aunt Liu nodded: "That's it." ”

"Then why didn't you call the police?" asked Yuan Shasha again.

Aunt Liu glanced at her, and said angrily: "Call the police, little girl, haven't I reported it?"

"In the past, when I lost something at home, the police at the police station, when they gave me a letter of approval, they all recorded it, and then asked me to wait. ”

"But why don't you give me time? I haven't had a letter for more than half a year, how can you let me believe you?"

"Then if you call my senior brother Gu, you will believe him?" Lu Weiwei heard it anyway.

The old lady's complaint against the police is not something that can be resolved in one or two sentences, it seems to be deep in the bone marrow.

From the words that came out of her mouth, it can be seen that this old lady has all kinds of complaints against the police, and there are many deep contradictions.

Aunt Liu also snorted coldly and said, "I don't believe the other policemen, but Gu Chen ......."

After glancing at Gu Chen up and down a few times, Aunt Liu said again: "He is different, he feels different from other policemen." ”

"Aren't they all wearing police uniforms? What's the difference?" The little nurse who had been spanked with a cane by the old lady before also interjected coldly in the crowd.

The old lady glanced at her and said coldly: "I don't know, anyway, you Gu Chen gives me a different feeling, at least you are better than those police officers at the police station, although you don't have jurisdiction over this area, you can tell the monitoring points in this area." ”

"It can be seen that you Gu Chen are still very concerned about work, at least you won't be like those policemen, who don't know anything. ”

"Hehe, Aunt Liu, I see that you are still prejudiced against the work of our police, in fact, ......"

"Needless to say, you don't have to defend those lazy colleagues, anyway, since I found you, then you have to keep your promise and help me find those hateful thieves. ”

Without waiting for Gu Chen to finish speaking, Aunt Liu directly preconceived and interrupted Gu Chen's words.

Not to mention how to deserve the name of an old witch and a community tyrant.

Gu Chen nodded: "Okay, I understand, but as far as you just said, we need to go to the scene to see, you see......"

Gu Chen glanced at Aunt Liu's head.

Aunt Liu also understood, and waved her hand directly: "My head is not made of dough, it's okay, I'll take you over." ”

"Okay. Before Gu Chen could speak, the middle-aged male doctor in a white coat walked over directly with ecstasy.

Feeling that Aunt Liu is leaving, she is as happy as sending away a plague god.

Aunt Liu was together, and the melon-eating crowd who were still crowded at the door of the infusion hall before were instantly frightened and retreated one after another.

Subsequently, Aunt Liu also swaggered out of the clinic, pointed to Gu Chen's police car and asked, "Take your car?"

"Take my car. Gu Chen nodded and said yes.

The old lady didn't see it, and after Gu Chen unlocked the car, she directly opened the rear door and sat in by herself.

Gu Chen drove away in a police car, and a group of doctors gathered around the community clinic breathed a sigh of relief.

The little nurse touched her forehead: "This old witch is finally gone, as soon as she comes, our clinic will make a fuss, it's really uncomfortable." ”

"Don't say it. The middle-aged male doctor on the side glanced at her, and said angrily: "Her brain was smashed by someone, but it didn't change, if she smashed her brain, then she wouldn't make trouble in our clinic." ”

"Huh?" The little nurse suddenly pulled the corner of the middle-aged male doctor's clothes and asked him shyly, "That police officer's name is Gu Chen?"

"Which police officer?" asked the middle-aged male doctor knowingly.

What the little nurse is thinking at this age, the middle-aged male doctor knows when he hears it.

The little nurse frowned slightly, and said angrily: "What other police officer? Isn't it the male police officer?" I see that the old lady is very polite to him, and I feel that he can lower the old lady. ”

"Haha. The middle-aged male doctor also laughed, and directly changed his face and said, "I don't know." ”

Little Nurse: "......"

......

......

On the other side, Gu Chen drove to the door of Aunt Liu's house, and Wang Xiaobao, the gatekeeper, seemed to feel the breath of the master, and screamed in the compound.

As soon as Aunt Liu's door opened, she said directly: "Come in, the house is in a mess, and I don't know who to reason with." ”

"How much have you lost?" Gu Chen followed behind her, and the law enforcement recorder kept on.

"There are always more than tens of thousands, my wedding jewelry, as well as some stamps at home, food stamps or something, those things are collectibles, and they are always valuable. ”

After thinking about it, Aunt Liu said again: "Oh yes, the most important thing is that my real estate certificate is gone, which is the certificate of my house, these guys even take this, it's too inauthentic." ”

"Understood. Gu Chen nodded, didn't speak anymore, and followed Aunt Liu directly into the house.

At the door, Gu Chen, Lu Weiwei and Yuan Shasha, the three of them put on white gloves and foot covers, respectively, and began to search the house.

According to Aunt Liu's remarks in the car before, Gu Chen first went to the kitchen window to check.

Sure enough, the old wooden window was cut open by the thief with a knife blade.

Through this small opening, the gangsters can easily pull the iron bolt away.

In addition, Aunt Liu's house belongs to an old mansion and does not have anti-theft windows, so the risk of anti-theft is extremely low, which also gives thieves an opportunity.

"Senior Sister Lu, are there any suspicious footprints near the door?" Gu Chen turned his head and asked Lu Weiwei in the living room.

"No, it's a bit dirty, but I don't think it's been cleaned with anything. Lu Weiwei said.

Gu Chen turned back to the living room directly, and according to Lu Weiwei's guidance, he really found the cat at the door.

Climbing into the room through the kitchen window, there was indeed some dirt on the windowsill, and according to the terrain outside the window, it was also a dirt floor.

According to Lu Weiwei's statement, it is clear that the thief is likely to climb into the room through the kitchen window and escape from the old mansion through the living room door.

There are obvious signs of being cleaned near the doorway......

Obviously, these thieves obviously noticed this, and they were afraid that their footprints would be exposed, so they cleaned them up with brooms.

"There is no trace, so how do you find it?" Aunt Liu frowned, and the whole person couldn't help but ask.

"Let's see if there are any other fingerprints. Gu Chen said.

Subsequently, everyone carried out a detailed search of all corners of the room, especially around the cabinet that was pried open, where fingerprints should have been left.

After extracting some fingerprints in the house, Gu Chen rubbed the fingerprint traces on the white paper, then glanced at Aunt Liu and asked, "Aunt Liu, can you leave your fingerprints?"

"Yes...... OK. Aunt Liu had never seen the police investigate a theft case, and she would be so meticulous, which was very different from her previous impression of the police, so she nodded and agreed.

Gu Chen took out a small box of ink, directly extracted Aunt Liu's fingerprints, printed them on another piece of white paper, and numbered them casually.

After repeatedly comparing two different fingerprint samples, Gu Chen used his specialization-level observation power to quickly find that the two fingerprints were actually from the same person, and he couldn't help but glance at Aunt Liu behind him.

"How...... How is it?" Aunt Liu asked weakly.

"This fingerprint is none other than your own. Gu Chen said.

"I ...... My own?" Aunt Liu was stunned, and she also felt incredible.

Gu Chen asked again: "Aunt Liu, do you live in this old mansion, have any guests visited during this period?"

"I didn't ...... No. Aunt Liu shook her head embarrassedly and said, "I've lived here alone all these years, and I haven't had any dealings with people, let alone guests." ”

"Is that no?" Gu Chen didn't want to hear too much explanation, so he asked the answer directly.

Aunt Liu nodded in confirmation: "No." ”

"The thief must have been wearing a defensive device. Gu Chen put away the two fingerprint samples, and said indifferently: "For example, protective equipment such as gloves is also to avoid leaving fingerprints at the crime scene." ”

Looking at Aunt Liu, who was stunned, Gu Chen said again: "It seems that you have met a habitual thief." ”

"That'...... Then there is no way to do it? can't you find them?" Aunt Liu was anxious, although she didn't show it too obviously.

But Gu Chen could still feel it.

"I'll ask you. Gu Chen found a wooden stool and sat down first, and asked Aunt Liu, "When did the crime happen?"

"No...... I don't know. Aunt Liu shook her head.

"Then when did you wake up?" Gu Chen asked again.

"No...... I don't know. Aunt Liu continued to shake her head.

Gu Chen pursed his lips and asked again, "Then what do criminals look like?"

"I don't know. Aunt Liu's answer was still the same.

Faced with Aunt Liu's questions and three questions, Lu Weiwei, who was standing on the side, was also anxious, and said directly: "I said Aunt Liu, you don't know this, you don't know that, this is quite troublesome, after all, we also need to know the time of the crime, right?"

"Even if fingerprints can't help us, if we know when the crime happened, it won't be difficult to find these people, you have to know at least something. ”

Aunt Liu's face was flushed when she was asked, and she lowered her head in embarrassment, as if she was also guilty of her carelessness.

"Bell! Bell......"

Suddenly, an ancient bell rang on the wall.

An old, age-sensitive clock is striking the time.

Yuan Shasha, who was standing on the side, was also instantly startled by this strange movement, and the whole person couldn't help but retreat.

At the same time as hearing the bell, Aunt Liu suddenly remembered something, and the whole person exclaimed: "Yes, I seem to know when those guys escaped." ”

"You know again?" Gu Chen turned his gaze to Aunt Liu again.

Aunt Liu's face was serious at the moment, and she also squinted her eyes and recalled carefully: "I remember that when those guys left, they were probably afraid that I would call the police, so they tied me to a wooden chair." ”

"They woke me up with such a toss, and although I couldn't see anything, I heard the bell. ”

"How many sounds?" Lu Weiwei hurriedly asked her.

"4 tones. Aunt Liu said.

Lu Weiwei was suddenly overjoyed, and she was also excited: "Great, so this gang of criminals fled the scene at 4 o'clock in the morning?"

"No...... Wrong. Aunt Liu suddenly looked stunned, and directly interrupted Lu Weiwei and said, "It's not 4 o'clock, it's 4 bells." ”

"4 bells ring, isn't it 4 o'clock?" Yuan Shasha on the side was also puzzled.

Aunt Liu was stunned, and directly waved her hand to explain: "That's different, it's not continuous, it's only heard once in a while." ”

"Is that the interval the same?" Gu Chen asked.

"Yes. Aunt Liu nodded.

"In other words, these four bells are heard by you uninterruptedly, and the length of each stage is the same, right?" Gu Chen asked again.

Aunt Liu still nodded and said, "That's right, these 4 bells rang every once in a while, I can't be wrong, they rang 4 times in total, and those guys only left when I heard the bell for the fourth time." ”

Gu Chen was a little confused, and turned his head to look at the ancient clock on the wall, a wall clock with a wooden square frame.

This type of antique was common in the rural areas of Jiangnan in the early years, but now most of them have been obsolete.

However, some well-preserved ancient clocks are still functioning normally.

Gu Chen remembered that the ancient clock of his uncle's house in the countryside was similar to this, and it was still working normally.

Walking under the ancient bell, Gu Chen turned around and asked Aunt Liu, "How does this bell ring?

"Half an hour later. Aunt Liu said.

"How many rings?" Gu Chen asked again.

Aunt Liu said: "Generally, within an hour and a half, it rings once, and after two o'clock, it rings according to the time number, two o'clock is two rings, two o'clock also rings twice, three o'clock rings three times, and so on." ”

Lu Weiwei couldn't help frowning and asked her, "You set the alarm clock in half an hour, aren't you annoyed by this bell?"

"Yes, it's usually set to ring once an hour, and you're too frequent for half an hour. Yuan Shasha on the side also agreed with Lu Weiwei's statement.

Normal people who are so boring?

Even the mobile phone modulates the alarm clock, and it is not so frequent, not to mention that the ancient clock is relatively old, and the alarm clock time cannot be adjusted at will according to the function of the mobile phone clock.

Aunt Liu also looked at everyone, and couldn't help but say: "I'm not afraid of your jokes, anyway, my old woman lives here alone, and I'm used to it, but sometimes it's very boring." ”

"When I'm bored, it's good to hear even a little movement, so I set the wall clock to ring every half an hour, which is quite fun. ”

Lu Weiwei glanced at Gu Chen, shrugged her shoulders and expressed helplessness, compared to the fun of the old lady, how could ordinary people know? Maybe the old lady was too lonely.

Gu Chen also understood and understood, so he took out his mobile phone and set the time with the wall clock on the wall.

"Your wall clock is six minutes slow. Gu Chen said.

Aunt Liu nodded: "That's right, it's slower." ”

"But, what time will it be?" Gu Chen couldn't help frowning, stared at Aunt Liu and said, "You said that you heard four rings, but according to what you said, except for 4 o'clock, you can't find 4 bells with the same interval, are you sure you won't be mistaken?"

"You can't be wrong, you can't be wrong. Aunt Liu also saw Gu Chen's questioning, and directly retorted:

"Every time I hear it, the interval is different, although my head was smashed at that time, and the whole person is dizzy, but I have a special sensitivity to the bell, and I can't be wrong. ”

"This is troublesome, is there something wrong with the wall clock?" Gu Chen hesitated for a moment, then pointed to the wall clock and asked Aunt Liu: "Then this wall clock, can you take it off and give me an experiment?"

"This ......" Aunt Liu hesitated for a moment, but quickly agreed: "Okay, but you have to be careful, this clock is old, don't smash it." ”

"No, don't worry. With Aunt Liu's consent, Gu Chen didn't have any scruples.

A small wooden chair was brought directly from the side and placed under the wall clock.

Then, he carefully stepped on the wooden chair and gently removed the dusty wall clock.

With the help of Lu Weiwei and Yuan Shasha, the three of them held the wall clock together and gently placed it on the table.

After consulting with Aunt Liu, Gu Chen began to conduct a model report experiment on the wall clock.

As I imagined, except for 4 o'clock and 4:30 o'clock, I couldn't find 4 bells with the same interval.

Gu Chen frowned, and he was also quite puzzled: "If you follow Aunt Liu's words, then this wall clock can only ring the bell at an interval of 3 times." ”

"It was 12:30 and 1 o'clock. At 1:30, there could be no more than that. ”

"Yes, what's going on? No matter how you say it, it will only make 3 sounds, how did you make 4 sounds?" Lu Weiwei was also even more foggy after Gu Chen's wave of mock report experiments.

It seems that Aunt Liu is a little confused, and there must be something wrong in some link.

"No...... No, I'm not mistaken. Seeing that this is the case, although Aunt Liu also felt inexplicable, she still insisted on believing that she had heard correctly.

The scene suddenly fell silent, and everyone looked at each other, as if the investigation had come to a brief standstill.

The clues are insufficient, or there are obvious flaws, but Aunt Liu insists again and again, which makes people feel suspicious.

Gu Chen didn't rush it, but took a pen and paper and began to draw the bell of the wall clock on the paper as an axis diagram.

At 12:30, Gu Chen drew the first point, the second point at 1 o'clock, and the third point at 1:30.

At 2 o'clock, Gu Chen didn't move.

"The bell rings at 2 o'clock twice, which is inconsistent with the interval that Aunt Liu said. Looking up at Aunt Liu, Gu Chen directly put a big cross at the 2 o'clock position.

"So...... Senior Brother Gu, what do you think is the most likely point?" Lu Weiwei couldn't guess either, so she had to ask Gu Chen.

Gu Chen directly picked up the pen and ticked it at 1:30.

"1:30?" asked Lu Weiwei, puzzled.

"That's right, the last time Aunt Liu heard it, it is also the time when the gangsters are most likely to escape, only 1:30 is the most appropriate. ”

Gu Chen then circled 1:30 with a pen.

Yuan Shasha was dumbfounded: "Can ...... But Aunt Liu heard 4 bells at the same interval, if according to Senior Brother Gu's words, 12:30, 1 o'clock, and 1:30 o'clock are indeed all bells, then where are the 4 bells at the same interval?"

......
